electric imp, inc 8 to 12, 14 to 16 PIN1, 2, 5 to E I/O, please refer to Pin mux table & 19 to 22 5. Pin mux In addition to acting as a GPIO, each pin on the imp002 can be configured to one of several specialized functions. While pins may only have one function at a time, they may be reconfigured during run-time to change function as needed. For example, a pin may first be configured as a DAC and then reconfigured as an ADC. Additionally, not all the pins in a hardware function need to be assigned to that function. For example, pins 8 and 9 could be used as UART and pins 1 and 2 could be used as I2C. All I/O pins are initially tri-stated. The imp002 can be woken from low power sleep mode with a rising edge on PIN1. If this signal is pulsed, the minimum pulse width is 20ms.
